I have sheepshaver running on a macbook pro 2016.Very nice. I've been using Turbosynth succesfully.I bought Sound designer 1.5 because you can make samples for many different samplers. Ive got MIRage I want to make sounds for, but sound designer is not working. Maybe because it uses Midi?I get this error upon opening"This Window cannot be opened because SDTemp-708109321"I can't open a sound file or make a new file to draw a sound. Nothing works. Help , and Thank you

Sounds like Sound Designer is trying to write a temp file somewhere it doesn't have write permissions. Do you have it installed on the boot partition of your SheepShaver OS 9 image? If so, did you install a full OS 9 on the image, or just use the preinstalled image from Redundant Robot that doesn't contain most of the software needed to support audio and video?

latest mac. touchbar. etc.I know about the Midi thing. I chose 1.5 because it has it specifically supports hardware samplers . You can load up support for the Mirage and it's OS and save in the sampler format. I was going to transfer to my g4 and send over midi.

I dont know what you mean by Guest OS: Mac OS 9.0.4

I did exactly what that kid did in the video. Then I went into unix and dragged turbosynth in and installed that way.

As SSW 7 seems to be the way to go, you might try SheepShaver with SSW 7.5.3 too.There is a bootable image here: http://macintoshgarden.org/apps/macos-753-emulatorsSheepShaver is way faster but is sharing the same limitation regarding MIDI.There is no support for MIDI in the source code since their common ancestor ShapeShifter for Amiga.

FusionPC for DOS has basic MIDI support.Alas Fusion needs some kind of DOS host and configuring MIDI in DOS plus routing to your MIDI box looks like a nightmare to me.In theory some SCSI to MIDI solution may be possible as Fusion supports SCSI flawlessly.Basilisk Build 142 for PC does support SCSi too, just a thought and a really long shot either way.
